Ethereum: How to batch multiple calls through a single function?

Bateching Change Kapuskusting The third selven function: intelligent approach contractor

Who builds intelligent contracts in the Ethereum block chain, developers from the challenge improves monolithic functions that are knit cards. In this art, we explore Holl for Banch through intelligent techniques mixed with one vaula.

The problem of monolithic functions

Monolith fires are configured to determine the shoulder manager. Separating Multipleve calls to lead to problems and the complexity of the Creator. For example:

Gas consumption : For each call, there is a gas cost, which can rise rapidly more than several requests.

Increen Complerity : With the corresponding complex functions, the contract is drawn up for maintaining and Debig.

Solution: Batch call third is a single function

To deal with these, we set the batch measurements with one function. This approach allLows:

Baatch Multiple Calls : We create one function of several income and performed them.

Contract structure

The three out of three of our contacts are starting: “Batchcall”, the action of the action “and the Shockleeror”. Batchcall is a functional multiple income, while the implementation of the acts of the law. Sleell functional is used to handle errors with Y during the batch.
